Hi Pierre-Emmanuel, It worked fine for me ~1 year until this update. I have passphrase-protected private key on Yubikey, and gpg-agent doesn't ask for the passphrase any more. No idea how to debug this issue, since there are many moving parts involved.
Various tweaks like export PINENTRY_USER_DATA="USE_CURSES=1" or setting pinentry-program /usr/local/bin/pinentry-curses in $GNUPGHOME/gpg-agent.conf didn't help. -- With best regards, Pavel Korovin
